Colors In order to distinguish this two pipes when hot-water pipe and cooling-water pipe are installed altogether, we directly import two colors PP-R raw materials from Borealis, blue color for cooling-water pipe, cafe color for hot-water pipe. 3.Pressure grade Our pipes includes S5, S4, S3.2, S2.5, S3.2 and S2.5 are applied to hot-water pipes system, S5, S4 and S3.2 are applied to cooling-water pipes system. When we design pipes system, safe coefficient is 1.25 or 1.5 depending on customers requires. International standard stipulated the safe coefficient of pipe system is 1.25 Pipe series S5 S4 S3.2 S2.5 Nominal pressure MPa (C=1.25) 1.25 1.6 2.0 2.5 Table 2 relations between pipe series and PN(C=1.5) Pipe series S5 S4 S3.2 S2.5 Nominal pressure MPa (C=1.5) 1.0 1.25 1.6 2.0 4.Specification and size The specification of pipe we are using are S series, expressed by nominal outside diameter multiplying nominal wall thickness(dnxen). Our company's raw material for PP-R hot-cooling water pipes, pipe fittings adopts the number which is same with North Europe PP-R. Specifications we possess are D20, D25, D32, D40, D50, D63, D75, D90, D110 xxxxx 4 meters each pipe, and also we can cut the length depended on customers requirements. |
